    Bitmap new_bmp = new Bitmap(width, height);
    new_bmp.setARGB(argb, 0, width, 0, 0, width, height);
    Graphics pen = Graphics.create(new_bmp);
    pen.setGlobalAlpha(Constants.TRANSPARENCY);
    pen.setColor(color);
    pen.fillRect(0, 0, width, height);
    return new_bmp;

    Bitmap bg = new Bitmap(width, height);
    Graphics pen = Graphics.create(bg);
    int x1 = width / 3;
    int x2 = x1 * 2;
    int y1 = height / 3;
